this morning the new controller for the NI has been updated after having re-evaluated the plant for NI (see entry https://logbook.virgo-gw.eu/virgo/?r=64736 )
the new controller is
# Etalon North boost 02
ACL_FILTER_SET Etalon_north_boost_02 1 35000 1 10
ACL_FILTER_ZEROS Etalon_north_boost_02 2e-07 0
ACL_FILTER_ZEROS Etalon_north_boost_02 2e-06 0.6
ACL_FILTER_POLES Etalon_north_boost_02 0 0
ACL_FILTER_POLES Etalon_north_boost_02 0 0
ACL_FILTER_POLES Etalon_north_boost_02 1e-5 0
Moreover the down conditon for long unlocks (like this commissioning break) is not optimal and it is better to discharge the offset at least once a day.
